Soft water
Ross, I can fully understand you as I remember quite well my time in Andalusia/Spain where water is so dreadfully hard and before I used to live in areas with soft water throughout my whole life.
Here in Leverkusen we have very soft water which comes from the big Dhünn-Reservoir, 15 miles up the mountains, which provides us with really tasty and very good soft water. I take a bottle full of it to the office every day to drink, as the water here in Cologne, on the other bank of the river Rhine is really dreadful! Very hard and terrible in taste!
The reservoir also feeds the river Dhünn from where the water originally comes and which is running along a few hundred yards from our house, flowing a few miles further down into the river Wupper (from which my native town has its name: Wuppertal = Wuppervalley) and both flow a few meters further, nearby Opladen, into Germany's biggest river: the Rhine - so far to Geography...lol All to be seen at Google Maps!
And I would always try to avoid to move to a place with hard water again!
